Let’s simplify the gun control question(s) and start out by looking at gun history.
1100 years of gun powder propellants - (invented by the Chinese during the Tang Dynasty in the 9th century)
700 years of direct fire, portable weapons (guns) - (invented by the Chinese in the 13th century)
235 years of repeating arms - (Girondoni air rifle 1780)
135 years of semiautomatic weapons - (Mannlicher Model 85, 1885)
Despite the ready availability of semi-auto guns for 135 years, it seems that only in the past 35 years that mass shootings have become a problem.
Therefore, the question that should be asked is, “What are the stimuli causing mass shootings?”
The answers to that question are not guns, nor the availability of semi-auto guns, nor easy access to guns as that has become more controlled and difficult and NOT easier. Therefore, given the history of guns more gun control cannot be the answer.
There is not a single answer to the question, and the answers are not simple. The stimuli causing mass shootings are multi-faceted. The stimuli for mass shootings are what need to be examined.
The Second Amendment states, "A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed."
Citizens ARE the militia. Given the chance we can, and will, defend ourselves. That is the part that is purposely being ignored by those calling for gun control as the simplistic answer - while refusing to acknowledge the difficult question of identifying the stimuli behind mass shootings.
